ODBC question

I am trying to connect to a DB2 v7.2 database from Lotus 123 v9.8
on a Windows XP Pro machine. I have the Software Development Client 
installed on the XP machine and have run the Client Configuration
Assistant and registered the SAMPLE and my TEST databases with the
ODBC Administrator as System DSN data sources. Everything seems
fine, but when I try to connect to "External Tables" through 123
my DB2 databases are not listed under available ODBC_data_sources.

The same setup works fine under WIN9x. Is there some sort of ODBC 
version difference between DB2 7.2 and Windows XP?

Any help appreciated.

Thanks,
Philip Wright
